Specification of Letters Patent.

Patented April 13, 1909.

To all whom it "may concern:

Be it known that l, Rossini. ll. Lnwrs, citizen of the United States, residing Providence, in the county of Provir ence a1 State of Rhode Island, have invented cc tian new and useful improvements in. Brac lets, of which the following is a specification.

lily invention relates to bracelets composed of a plurality of connected expansible units, and has for its objects the provision of easily slidable connecting members; a novel and secure mounting for the springs adapted for facile reception thereof; and an inexpensive and strong means for prevent ing excessive distention of the springs.

Figure 1 is a plan elevation of a bracelet embodying my invention, Fig. 2, a vertical central section of a portion of the bracelet showing the parts in contracted position, Fig. 3, a like section of the same showing the parts expanded, Figs. 4 and 5, sections on line as no of Fig. 2 and on y y of Fig. 3 respectively, Fig. 6, a perspective view of one of the units with its face plate removed, and Fig. 7, a perspective View of one of the connecting members.

Like characters of reference indicate like parts throughout the views.

My bracelet comprises a series of shells or units, A, expansibly connected by members hereinafter described. ln detail, the units are composed of tee inner and outer walls, a and a the former being preferably curved; also end walls, a and a preferably inclined; and side walls, at and a In manufacture, it is convenicnt to form the walls, a, a, (1, at, and c in one piece, and solder or otherwise fix the front wall or plate, a, to the side and end walls. The end walls, a and of are provided respectively with vertically disposed oblong slots or openings, a and (L The connecting members, B, consist of a series of flat plates, links, or frames struck up out of sheet metal. They are substantially rectangular in outline and in detail of the following construction. One end of the plate, B, is provided with lateral lugs or projections, l), b. Upon each side of its center the plate is cut out to form two paral lel longitudinal slots, 6, b and a transverse slot, I), connecting the longitudinal slots at about one-third their length, which form oppositely disposed integral long and short projections, D and b respectively. in the plate a point intermediate the slots, 2 0 is cut tongue, G, wl'iose end extends out of the plane of the plate and is purposed as a stop.

in assembling the members, A and latter is passed through the slots, (1." of adjacent unit walls until the l 's, the frame abut again t tl inner fut. wall (L2 in I tongue, G, whic is of springy mate ial and .irected towari-L the end of the plate, 3, which carries the lugs, 5, presents no obstruction to the dcscnbed introduction of the plate.

Upon each pair of projections, b if is mounted helical spring, D. These are aplied by introducing one end of the spring through the slot, and over and along the projection, 6 and compressing the coils thereon sufliciently to permit the other end of the spring to be brought into alinement with the projection, 6 whereupon the spring is released and surrounds the latter projection. The projections upon which the springs are thus mounted form a stiff guide, bearing, and support throughout their length which prevents buckling, strain, and dislodgment. Cne end of each spring rests against the portion of the plate adjacent the base of the projection, 1?, while its other end bears against the inner face of the end wall, c Excessive longitudinal strain upon the sorings which might otherwise result in setting the same, is prevented when the units are expanded. by the contact of the free end of the tongue, 0, against the inner face of the wall, a

it will be noted that the several parts are simply and inexpensively constructed, and easily assembled.

he lateral lugs, b, may omitted, and the slots, b may be extended to one of the end margins of the plate, B, without departing from the spirit of my invention; but obviously with some resulting irregularity in the outline of the bracelet, and with a loss of strength in the plate.

Other changes and modifications of my invention will occur to those skilled in the art.

l v'hat I claim is,

1. In a bracelet, a connecting link, projections in the link in longitudinal alinement with each other, and an actuating spring upon the projections.

2. In a bracelet, a flat connecting link, op positely disposed projections in the link, an actuating spring upon the projections, and a tongue upon the face of the link.

3. In a bracelet, a flat connecting link oppositely disposed integral projections upon the link and in the plane of the link, an actuating spring mounted upon the projections, and an integral tongue upon an intermediate portion of the link projecting out of the plane of the link.

4. In a bracelet, a flat connecting link provided with lateral lugs, oppositely disposed projections in the link, and an actuating spring upon'the projections.

l expansible units, each i 1 spring in each opening mounted upon the projections and stopping means upon the a link.

I 8. A bracelet composed of'a plurality of unit consisting of a shell, a Hat connecting link slidably mounted in the shell and provided upon opposite sides 5. In a bracelet, a flat connecting link pro- I of its center with oblong openings, projecvided with integral lateral lugs, opposltel trons 1n the link extending into each of the disposed integral projections upon the link and in the plane of the link, an actuating spring mounted upon the projections, and an integral tongue upon an intermediate por tion of the link.

6. In a bracelet, a flat connecting link provided With an opening integral projections upon the link extending into the opening, a spring upon the projections, and a stopping l I j in the link intermediate the openings. I

openings, a spring in each opening mounted upon the projections, and a stopping device In testimony whereof I have aflixed my i signature in presence of tWo Witnesses.
